This list reviews the best online brokers for trading internationally in 2016. To qualify, online brokers must be based in the United States, regulated by the United States, and offer international investors outside of the United States access to trading US securities. Before choosing a brokerage, make sure to check directly with the broker and confirm they support your country of residence.

As an example, here is a list of the international countries that OptionsHouse currently accepts new customers from: Germany, Hong Kong, India, Singapore, Taiwan (Province of China), the United Kingdom, and the United States. If you live in any of these countries, OptionsHouse will allow you to open a brokerage account online and invest in US securities including stocks and options.

Currently, there are only select US online equity brokers that support non-US citizen clients. This is mostly due to the complexities surrounding regulation, customer support, language, paperwork, etc. Note that this tool is designed to help foreign investors trade on the US exchanges, not help US citizens invest internationally. If you reside in the United States and want to invest on foreign exchanges using local currency, the two best brokers to look at are Interactive Brokers and Fidelity Investments.
